NFV● Optimized (Energy & Network Efficiency)

● For Service Provider

● NFV Value Proposition

○ NVF is a killer use-case for Openstack

● Call for community action○ Scheduler Gap and a candidate solution [e.g.SolverScheduler, blueprint exists, code

pushed for review in Icehouse]

○ Cross-Scheduler API w. constraints [e.g. augment server-groups API released in

Icehouse]
